ULVERSTONE woman Natalie Daley has been flooded with hundreds of messages of support after her decision to begin a petition to lobby the state government for the legalisation of medicinal cannabis.

Mrs Daley, who is living with adrenal gland carcinoma, posted on her Facebook page, Natalie's Journey, a request for support if she was to start a petition about the legalisation of medicinal cannabis.

"I've just had such a response, it's a bit overwhelming," the mother of three said.

"I've had people I know and complete strangers get in contact with me and everyone is in support of it [legalisation].

"I'm always on my phone now. I can't keep up."

Mrs Daley said she expected to receive some hate mail or negative comments when she went public with the admission that she herself used the illicit substance, but said she had seen none of that at all to date.

Mrs Daley uses cannabis oil to relieve the side-effects of chemotherapy treatment and remains convinced the oil has helped to shrink her tumour.

The petition is yet to be officially started, but Mrs Daley said she was working towards getting all the paperwork official and said she wasn't sure whether she would post it online or specifically on Facebook.

She said she was disappointed with the way the state government had handled the issue so far and said it was time ministers "opened their eyes" to the benefits that it was giving to thousands of sick people.

"It's not only for me, but I want other people to be able to access it, they're just looking for a shot, just like me," she said.

Mrs Daley said she thought the government was losing sight of what medicinal cannabis use would mean and said it was too caught up in the recreational use debate.

"There's a difference between using it for medicinal use and using it just to get high," Mrs Daley said.

Health Minister Michael Ferguson was contacted for comment and a spokesman released this statement: "We don't support a trial in Tasmania.

"The reasons have been well articulated and we're not going to go over them again."
